Source Of Essential Potassium

Sturdy Stalk supplies potassium, an essential nutrient for plants. Potassium plays a vital role in water and nutrient transportation within the plant. It also activates enzymes responsible for producing proteins and starches, which serve as energy sources for plants.

Strengthens Plant Structure

Sturdy Stalk acts as a "cement" for individual cell walls, making them stronger and more resilient. It forms a protective barrier that prevents damage from external factors and promotes water retention. This helps plants withstand droughts and high temperatures.

Enhances Fruit & Flower Pigments

Sturdy Stalk contributes to bountiful blooming by promoting the formation of fruits and flowers. Potassium is involved in the production of cell sap, which stores pigments. Increased levels of cell sap result in brighter and more vibrant blooms.

Super Easy To Use

Sturdy Stalk can be applied when needed and has no specific feeding routine. It can be used throughout the growth cycle, from early vegetation to late flowering. For best results, apply Sturdy Stalk on regular watering days and avoid using it with Emerald Harvest Cal-Mag in the same watering.

Designed For Hydroponic Use

Sturdy Stalk is recommended for use in hydroponic systems, including reservoirs, tanks, and drain-to-waste and recirculating systems.

Sturdy Stalk provides soluble silicon derived from potassium silicate, fortifying plant cell walls and protecting against pests and diseases. It improves water retention, resulting in more resilient plants. Additionally, it enhances fruit and flower pigments, leading to brighter and more vibrant blooms. Sturdy Stalk can be applied as needed and is suitable for use in hydroponic systems.
